The brownfield project hosts a past producing mine which closed in 1992.
The scope of the contract with Snowden extends to all aspects of the project through to the application for a mining licence, the company said.
In the near term the work will involve upgrading the project’s current JORC resource.
Snowden will send a team to visit the site in Namibia next week and the early work will involve desktop reviews of tailings dumps, the in-situ ore within the historic mine.
As it progresses the project the consultant will also review tailings retreatment, design drill programmes, mine design and scheduling, ventilation, metallurgy, process flow sheets, and a detailed cash flow model.
With Snowden’s appointment the project is now moving on schedule into the second stage of the three stage plan as set out by managing director Martin French.
"The engagement of a single consulting group to advise on all aspects of the project is an important step forward for the development of Namib,” French said in a statement.
“It provides us with a clear structure and timeframe for the project, which we are now moving up through the gears."
